Scope

Scope: This standard specifies the requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for crude copper. This standard applies to crude copper produced by melting and casting copper substrates after removing gold and silver, and is intended for refining purposes. For the production and use of this product, in addition to complying with this standard, it shall also comply with relevant national, local, and industry regulations, norms, and standards. Main technical content: The crude copper grade specified in the standard is Cu90.00. The chemical composition shall comply with the requirements specified in the table below: Grade Cu Impurities As Sb Bi Pb Cu90.00 C90.00 0.50 0.40 0.10 0.6 Cu80.00 C80.00 0.50 0.40 0.10 0.6 Cu70.00 C70.00 0.50 0.40 0.10 0.6 Cu60.00 C60.00 0.50 0.40 0.10 0.6 The arbitration analysis method for chemical composition shall be conducted in accordance with the provisions of YS/T 521 (all parts), and the physical specifications shall be inspected using corresponding measuring tools. The surface quality shall be inspected visually. Inspection rules: Crude copper shall be inspected by the supplier's technical supervision department to ensure that the product quality complies with the requirements of this standard, and a quality certificate shall be filled out. Crude copper shall be submitted for inspection in batches, each batch consisting of products from the same furnace. The chemical composition shall be inspected by batch, and the physical specifications and surface quality shall be inspected block by block. The numerical values of the chemical composition inspection results shall be rounded in accordance with the provisions of GB/T 8170. The crude copper ingots shall bear the manufacturer's product mark, and each crude copper ingot shall be marked with the batch number, weight, and grade in a clear color. Each batch of crude co
